JOSEPH LAPOINTE, OF WEST WARREN, MASSACHUSETTS.

. RATCHET-WRENGH.

Specification .of Letters Patent.

Patented Nov. 25, 1919.

Application filed July 27, 1917. Serial No. 183,160.

To all whom it may concern:

Be it known that I, Josnrn LAPOINTE, a citizen of the United States, residing at West Warren, in the county of Worcester,

State ofMassachusetts, have invented certain new and useful Improvements in Ratchet-Wrenches; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Tl is invention is an improvement in wrenches and has particular reference to a trating the invention, is shown in the accompanying drawing, wherein Figure 1 is a side elevation of the wrench constructed in accordance with the inventicn.

Fig. 2 is an edge elevation thereof.

Fig. 3 is a longitudinal section therethrough.

Fig. 4: is a detail perspective view of one of the socket members employed in connection with the invention.

Fig. 5 is a similar View of the socket operating element.

In the drawing the numeral 10 indicates the handle of a wrench having preferably formed inte rally with one end thereof the cylindrical head 11 provided at each end with the ratchet 12, the teeth of one end extending in opposite directions from those of the other end. The element 11 is provided with a longitudinal opening 13 in which is mounted the pivot bolt 14 about which said element is adapted to rotate.

Each end of the bolt 14 supports a sleeve member 15 and since these sleeve members are substantially identical in construction a description of one will suflice for both.

The inner end 16 of each sleeve member is provided centrally thereof with an opening 17 for receiving the adjacent end of the bolt 14: and said inner end is also provided with an annular flange 18 adapted to engage the adjacent end of the element 11 and surround an annular row of ratchet teeth formed upon said end l6 and adapted for engagement with .the ratchet 12 on the ad- ]acent end of the head 11. The only diiierence in construction between the two sleeve members 15 is that the teeth 19 of one extend in an opposite direction from those of the other and one of said sleeve membersis to be employed in threading a nut upon the bolt, while the other sleeve member is used to unscrew the nut.

- Each end of the bolt 14 is screw threaded as indicated at 20 and receives thereon a washer 21 and a nut 22 which fits snugly in the sleeve member, said washer 21 forming an abutment for one end of a coil spring 23 the other end of which engages the inner end '16, of the sleeve member and thereby yieldably retains the teeth thereof in engagement with the teeth 12 on the head 11. It will be. understood that when assembling this wrench, after the bolt 14 has been mounted in position in the head 11, the spring 23, washer 21 and nut 22 are successively placed in each sleeve member and the latter then mounted over the end of the bolt l i so that the nut 22 will engage the threads 20 and by rotating said sleeve member said nut will be threaded upon the bolt. Each sleeve is formed at its outer end to constitute a nut engaging socket and by reason of the sleeves being held by the nuts, they may be of course substituted by other sleeves to receive other sized or shaped nuts, when desired.

/Vhat is claimed is A ratchet wrench comprising ahead having a handle and an axial bore, a bolt rotatable in the bore, a sleeve for each end of the bolt having a perforated web between its ends in which the bolt is received, the sleeves at the inner ends having each a ratchet connection with the corresponding end of the head engageable in opposite directions of rotation of the head, nuts engaged with the ends of the-bolt at the outer sides of the webs, and a spring within each sleeve between its web and the correspond- JOSEPH LAPOINTE.
